LightWave + Houdini


chang

Recommended Posts

I've read Calosus's post about houdini + lightwave.

I also have interest on H + LW cooperation.

What I want to accomplish is,

level 1. import LW object, tweak surface by Houdini operators, put the obj back to LW.

level 2. import LW animation, build particles on LW surface by POP, render on vexMantra.

level 3. same as above, but sending back the animation to LW, render on LW.

What a way to go. I wonder how tough this would be.

Task 1 was a easy one.

You can import .obj by FileSOP. Export by GeometryROP.

I'm working on Task 2 now.

Can anyone point me to LW scene file description?

I made y position key frames.

Below is excerpts from LW scene file.

No need for that. We should be, at least I am, concentrating on making a MOT (LWMOT; a.k.a. LightWave Motion) interpreter. Really, just automating the manual conversion between LW and Houdini.

And importing objects with textures shouldn't be such a big deal. Since LW6.* finally supports UV-mapping. And since LW7.* you can export LWO's (or OBJ's) with maps intact aswell!
